BACKGROUND Technical Field

The present invention relates to the field of cigarettes, and inparticular to a dual-use cigarette with the advantages that cold aircannot be sucked when smoking is started, and the burn of a respiratorymucosa caused by high temperature smoke can be avoided.

Related Art

With the rising of anti-smoking campaigns at home and abroad, as well asthe gradually expanded scope of smoking bans in public places at homeand abroad, the research and development of heat not burning (HNB)tobacco products have become one of the research hotspots of tobaccocompanies in many countries in the world. The so-called HNB tobaccoproducts refer to the tobacco products produced by “heating tobaccoshreds or tobacco extract to generate smoke”, and avoid high-temperaturepyrolysis of tobacco combustion, thereby greatly reducing the amount ofrelease of harmful components in mainstream smoke. Meanwhile, becausethe tobacco shreds are not burned, the environmental smoke is greatlyreduced. However, for the existing dual-use cigarettes, when the smokingis started, cold air will be sucked to cause discomfort. When in heavysmoking, the high-temperature smoke will burn a respiratory mucosasometimes and cause harm to a human body.

SUMMARY

An objective of the present invention is to provide a dual-use cigarettewith the advantages that cold air cannot be sucked when smoking isstarted, and the burn of a respiratory mucosa caused by high temperaturesmoke can be avoided.

The present invention is implemented by the following technicalmeasures: a dual-use cigarette comprises a suckable material segment anda filter tip segment which are wrapped by roll paper, wherein a hollowedsegment surrounded by the roll paper is disposed between the suckablematerial segment and the filter tip segment, and the roll paper of thehollowed segment is provided with a plurality of first capillary pores.

As a preferred embodiment, the roll paper of the filter tip segment isprovided with a plurality of second capillary pores.

As a preferred embodiment, a diameter of the first capillary pores issmaller than or equal to a diameter of the second capillary pores.

As a preferred embodiment, the first capillary pores are away from theend of the filter tip segment by 2 mm-3 mm, a degree of aeration of thefirst capillary pores is 100 CU-600 CU, the first capillary pores are intwo rows, and a length of the hollowed segment is 5 mm-35 mm.

As a preferred embodiment, the suckable material segment is a tobaccoproduct segment.

As a preferred embodiment, a suckable material in the suckable materialsegment is filiform, granular or flaky.

As a preferred embodiment, the roll paper is roll paper for cigarettes.

As a preferred embodiment, the roll paper is roll paper for cigars.

As a preferred embodiment, a length of the filter tip segment is 5 mm-25mm, and a suction resistance of the filter tip segment is 2000 Pa-5000Pa.

The present invention mainly uses an electric heating device to bake thesuckable material segment, such that volatile substances (such as aromasubstances and nicotine, etc., of the tobacco) are volatilized forpeople to suck. Since the hollowed segment is disposed between thesuckable material segment and the filter tip segment, the volatilesubstances (smoke) volatilized by heating before the suction are storedin the hollowed segment, and the scented gas can be sucked when peoplestart to suck. Since the plurality of first capillary pores is disposedin the roll paper of the hollowed segment, the cold air in the hollowedsegment originally is discharged from the first capillary holes whilethe volatile substances are stored in the hollowed segment, so as toavoid the discomfort caused by suction of the cold air when the smokingis started. Due to the small aperture of the small first capillarypores, the gas flow can be formed only under a certain pressuredifference. The plurality of first capillary pores is disposed in theroll paper of the hollowed segment, and during the suction, the cold airfrom the outside can be sucked to cool the sucked high-temperaturesmoke, and the high temperature smoke is prevented from burning therespiratory mucosa.

DETAILED DESCRIPTION

The present invention is further explained in detail in combination withthe embodiments and in accordance with the accompanying drawings.

A dual-use cigarette, referring to FIGS. 1 and 2, comprises a suckablematerial segment 6 and a filter tip segment 1 which are wrapped by rollpaper 5, wherein a hollowed segment surrounded by the roll paper 5 isdisposed between the suckable material segment 6 and the filter tipsegment 1, and the roll paper of the hollowed segment is provided with aplurality of first capillary pores 4.

The present invention mainly uses an electric heating device to bake thesuckable material segment, such that volatile substances (such as aromasubstances and nicotine, etc., of the tobacco) are volatilized forpeople to suck. Since the hollowed segment is disposed between thesuckable material segment and the filter tip segment, the volatilesubstances (smoke) volatilized by heating before the suction are storedin the hollowed segment, and the scented gas can be sucked when peoplestart to suck. Since the plurality of first capillary pores is disposedin the roll paper of the hollowed segment, the cold air in the hollowedsegment originally is discharged from the first capillary holes whilethe volatile substances are stored in the hollowed segment, so as toavoid the discomfort caused by suction of the cold air when the smokingis started. Due to the small aperture of the small first capillarypores, the gas flow will be formed only under a certain pressuredifference. The plurality of first capillary pores is disposed in theroll paper of the hollowed segment, and during the suction, the cold airfrom the outside can be sucked to cool the sucked high-temperaturesmoke, and the high temperature smoke is prevented from burning therespiratory mucosa.

According to the dual-use cigarette of the present invention, referringto FIG. 1 to FIG. 2, based on the foregoing technical solution,specifically, the roll paper 5 of the filter tip section 1 is alsoprovided with a plurality of second capillary pores 2.
